[0034] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0035] This application discloses a roll paper tray for a printer. (See also...) Figure 1 and Figure 2The paper tray for the printer includes a tray body 1, which can be made of any material such as paper or plastic. The tray body 1 has an openable and closable cover 2. The tray body 1 is used to hold printing paper, allowing the printing paper to be stored directly inside the tray body 1 without the need for additional storage space, which is convenient for storing printing paper and saves space. The tray body 1 has a paper outlet 3 along its length for pulling out the printing paper. The width of the paper outlet 3 extends through two adjacent sides of the tray body 1. When in use, part of the paper outlet 3 faces the printer and part faces upward, so that the printing paper can be pulled out along the diagonal position of the tray body 1. The part of the paper outlet 3 facing the printer makes room for the lower part of the printing paper, and the part of the paper outlet 3 facing upward makes room for the upper part of the printing paper, so that the position of the printing paper can be better adjusted when pulling it into the printer. It can be well matched with the printing paper inlet of portable printers and is easy to operate. The tray body 1 can limit the printing paper without the need for additional support to fix it, thereby improving the convenience of use.

[0036] In some embodiments, the cartridge 1 also has a recess 4 that penetrates the paper outlet 3. The recess 4 is located on the top of the cartridge 1 and is arc-shaped to better accommodate the finger pulling out the printing paper.

[0037] In some embodiments, caps 2 are provided at both ends of the box body 1 along its length, meaning that both ends of the box body 1 are open, and the caps 2 are used to seal the openings. This allows the box body 1 to be opened from any direction to insert printing paper.

[0038] In some embodiments, the cover 2 includes a sealing part 21 and a connecting part 22. The sealing part 21 can be bent and connected to the end of the box body 1. The connecting part 22 and the sealing part 21 can be bent and connected. After printing paper is placed in, the sealing part 21 is bent and covered at the end of the box body 1, and the connecting part 22 is bent and snapped into the box body 1.

[0039] In some embodiments, the cover 2 further includes a snap-fit ​​portion 23, which is foldable and connected to the box body 1 on both sides adjacent to the sealing portion 21. When the cover 2 is closed, the snap-fit ​​portion 23 is folded and covers the end of the box body 1, and the sealing portion 21 is bent and abuts against the snap-fit ​​portion 23 and covers the end of the box body 1. The snap-fit ​​portion 23 enables the cover 2 to be more stably connected to the box body 1.

[0040] Reference Figure 3 and Figure 4 In some embodiments, an adjusting member 5 is also included, which is disposed inside the housing 1 near the end. In this embodiment, the adjusting member 5 is a cuboid or cube block structure, and all six sides of the block structure adjusting member 5 have a large contact area, so that it can be stably placed inside the housing 1 to limit the position of the printing paper.

[0041] In some embodiments, at least two adjusting members 5 are provided, symmetrically arranged at both ends of the housing 1. In this embodiment, when an adjusting member 5 is provided at each end of the housing 1, the length of the printing paper is just enough to be pulled out along the paper outlet 3. Smaller sizes of printing paper can be accommodated by continuing to add adjusting members 5 of different or the same size. In other embodiments, the length of the paper outlet 3 can also be increased, and the size of the adjusting members 5 can also be set according to actual conditions to accommodate different sizes of printing paper.

[0042] In this embodiment, the adjusting member 5 is made of foam. Foam is lightweight, allowing for size adjustment while controlling the weight of the paper roll, and it also prevents damage to the ends of the printing paper. In other embodiments, the adjusting member 5 can be made of any material such as plastic or paper.

[0043] The implementation principle of a roll paper tray for a printer according to an embodiment of this application is as follows: When the printing paper is not in use, it can be directly stored in the tray body 1 without the need for additional storage space, which is convenient for preservation; when in use, the roll paper can be pulled out directly from the paper output port 3, and the tray body 1 is placed on one side of the portable printer. Since the paper output ports 3 penetrate through the adjacent two sides of the tray body 1, the angle can be adjusted more easily when the printing paper is pulled out, which can correspond well to the printing paper inlet of the portable printer and is easy to operate. The tray body 1 can limit the printing paper without the need for additional brackets for fixation, thereby improving the convenience of use.

[0044] This embodiment also discloses a portable printer. (Refer to...) Figure 5 and Figure 6 The portable printer includes a printer body 6 and the aforementioned paper roll cassette for printing. The paper output port 3 is positioned corresponding to the paper inlet of the printer body 6. In this embodiment, the paper output port 3 extends through two adjacent sides of the cassette 1 in the width direction, which allows for better adjustment of the paper output direction and more stable insertion into the paper inlet of the printer body 6, thus enabling better printing. Since the cassette 1 has a limiting and fixing function for the printing paper, the position of the paper roll cassette can be arbitrarily adjusted according to spatial location and other needs, making it more flexible to use.

[0045] In some embodiments, the housing 1 is connected to the printer body 6. The housing 1 can be detachably or fixedly connected to the printer body 6 by any means such as adhesive backing, snap-fit, or plug-in, which can not only fix the housing 1, but also save space and facilitate the carrying and use of the portable printer.
